Abstract

A red iron oxide pigment (I) has a color saturation value (C asterisk ) of greater than 39 Cielab units. An Independent claim is included for the preparation of the pigment (I) by producing a fine suspension of hematite by mixing dilute nitric acid with elemental iron at above 90 degrees C followed by reaction of the suspension with iron (II) salts and alkali hydroxide in the presence of an oxygen containing gas or reaction of iron, iron (II) salt and oxygen-containing gas to form a hematite pigment suspension with optional isolation of the resulting pigment.
